Does anyone know where to find it? I understand there are online resources, but I'd like to take a shot at adding this feature to my brew day spreadsheet.
The best calculator for translating post ferment Brix readings to gravity readings that I have found is produced by Sean Terrill.
See http://seanterrill.com/2011/04/07/refractometer-fg-results/ for details. He even provides spreadsheet templates for your convenience.
Personally, if there's any doubt, I take Brix readings to determine when fermentation is finished, and then take a single gravity reading with an hydrometer to determine what the final gravity is, and to judge the taste of the sample.

Got the spreadsheet, will do my own comparisons. One of the reasons I do 4 weeks primary is to ensure the beer fully attenuates. Don't want to take the loss of a cylinder of wort daily. Hoping that with the smaller sample needed for a refractometer, I can take more frequent samples.
A point of edification; Why is Brix used in the calculators as opposed to SG? I have a dual scale refractometer, so I can use either. Just wondering.
